Description

Technical Field

[0001] The present application relates to the technical field of water purification equipment, and in particular to a vibration-reducing and noise-reducing water purifier. Background Art

[0002] Water purifiers with heating function (hot small purifier, purifier and heat all-in-one machine, etc.) have gradually become the mainstream water purifiers on the market and are loved by people. At present, commonly used water purifiers all use water pumps to pump water. The water pump is installed on a waterway board, which is fixed on the main frame of the whole machine. The natural frequency of the waterway board used to meet the flow demand is easy to be close to the vibration main frequency of the water pump. In the water production process, the water pump is used as a power, and the vibration of the water pump is transmitted to the waterway board, causing the waterway board and the water pump to resonate. The waterway board then transmits the vibration to the main frame, causing the whole machine to resonate, resulting in a large noise of the whole water purifier, affecting the user experience. Utility Model Content

[0003] The present application provides a vibration-reducing and noise-reducing water purifier, which can improve or solve the technical problems of the above-mentioned existing water purifiers with obvious vibration and high noise to a certain extent.

[0004] The technical solution adopted in this application is:

[0005] A vibration-reducing and noise-reducing water purifier comprises a main frame, a hot water pump, an inlet waterway plate and an outlet waterway plate, wherein the inlet waterway plate is provided with an inlet pipe, the outlet waterway plate is provided with an outlet pipe, the inlet pipe is connected to the water inlet of the hot water pump, the outlet pipe is connected to the water outlet of the hot water pump, the inlet waterway plate is separated from the main frame, the main frame is provided with a limiting connection part, the outlet waterway plate is provided with a matching part, and the main frame is connected to the outlet waterway plate through the matching and limiting connection part.

[0006] The vibration and noise reduction water purifier in this application also has the following additional technical features:

[0007] The water purifier also includes an elastic vibration reduction structure, which is arranged between the limiting connection part and the matching part to play a buffering and vibration reduction role between the water outlet waterway plate and the main frame.

[0008] One of the limiting connection part and the matching part is configured as a through hole, and the other is configured as a column adapted to the through hole. The column and the through hole are inserted and limited to cooperate with each other, and the elastic vibration damping structure is configured as an elastic pad clamped between the column and the inner wall of the through hole.

[0009] A limiting end is provided at the end of the column, and the limiting end includes two symmetrically arranged limiting clips. After the column passes through the through hole through the limiting clips, it is clamped and limited to the water outlet waterway plate. There is a gap between the two limiting clips so that they can deform toward each other when pressure is applied to reduce the outline size of the limiting end.

[0010] The elastic pad includes an annular body with an axial hole, and the two axial ends of the annular body are respectively provided with positioning protrusions extending radially outward. The two positioning protrusions respectively abut against the end surfaces of the through hole at both ends to limit the axial movement of the elastic pad, and the column passes through the axial hole.

[0011] One of the limiting connection portion and the matching portion is configured as a slide groove, and the other of the two is configured as a slider adapted to the slide groove. A stop portion is provided in the slide groove, and the slider slides into the slide groove. The stop portion cooperates with the slider stop to limit the slider from sliding out of the slide groove, and the elastic vibration damping structure is configured as an elastic pad wrapped around the outside of the slider or attached to the inside of the slide groove.

[0012] The water outlet pipeline has a connection port for connecting to the water outlet of the hot water pump, and the distance between the matching portion and the connection port is L, 1cm≤L≤2cm.

[0013] The ratio of the mass of the water inlet waterway plate to the mass of the water outlet waterway plate is 0.8-1.2.

[0014] The water purifier also includes a water tank installed in the main frame, the water tank is provided with a water supply pipe with a water supply outlet, the water supply pipe is connected to the water inlet pipeline, and the water inlet waterway plate is separated from the main frame by being connected to the water supply pipe and the hot water pump respectively.

[0015] The water purifier also includes a filter element, an instant heating body and a cold water pump respectively installed on the main frame. The water storage tank is configured as an insulation box with a heat preservation function. The clean water outlet of the filter element is connected to the water inlet of the instant heating body, and the water outlet of the instant heating body is connected to the insulation box. The water outlet waterway plate is provided with a normal temperature water pipeline. The water inlet of the cold water pump is connected to the clean water outlet of the filter element, and the water outlet of the cold water pump is connected to the water outlet pipeline through the normal temperature water pipeline.

[0016] Due to the adoption of the above technical solution, the technical effects achieved by this application are:

[0017] 1. The vibration and noise reduction water purifier provided in the present application has a water inlet water circuit board provided with a water inlet pipe, and a water outlet water circuit board provided with a water outlet pipe, the water inlet pipe is connected to the water inlet of the hot water pump, and the water outlet pipe is connected to the water outlet of the hot water pump. In other words, the water inlet and the water outlet of the hot water pump are respectively connected to the water inlet water circuit board and the water outlet water circuit board to achieve a cross-board connection. In this way, the situation where the vibration main frequency of the water pump is consistent with the fixed frequency of a water circuit board can be changed. When the water inlet water circuit board and the water outlet water circuit board are each independent, their mass is greatly reduced relative to the mass of the entire water circuit board, and the fixed frequency will also be greatly reduced, thereby avoiding the working frequency of the hot water pump, which helps to avoid resonance with the hot water pump. In addition, the water inlet waterway plate is separated from the main frame, and the water outlet waterway plate is limited on the main frame. Therefore, compared with the method in which both the water inlet waterway plate and the water outlet waterway plate are in contact with the main frame, in this solution, the water inlet waterway plate is completely not in contact with the main frame, so that the water inlet waterway plate cannot directly transmit vibration to the main frame. Therefore, the degree of resonance generated by the main frame is greatly reduced, thereby effectively reducing the working noise of the whole machine and improving the user experience.

[0018] 2. As a preferred embodiment of the present application, an elastic vibration-damping structure is arranged between the limiting connection part and the matching part to play a buffering and vibration-damping role between the water outlet waterway plate and the main frame. Therefore, compared with the method of hard connecting the water outlet waterway plate and the main frame, under the buffering and vibration-damping effect of the elastic vibration-damping structure, the water outlet waterway plate and the main frame form an elastic soft connection. After the vibration energy of the hot water pump during operation is transmitted to the water outlet waterway plate, the water outlet waterway plate converts most of the vibration energy into elastic potential energy of the elastic vibration-damping structure. The vibration energy is greatly absorbed and attenuated by the elastic vibration-damping structure, thereby greatly reducing the vibration energy transmitted to the main frame, thereby effectively reducing the vibration of the whole machine and achieving the effect of noise reduction.

[0019] 3. As a preferred embodiment of the present application, the water outlet pipe has a connection port for connecting to the water outlet of the hot water pump. The vibration energy generated when the hot water pump is working is transmitted to the cold water pump through the connection port. Therefore, the vibration at the connection port of the water outlet waterway plate is the most obvious position relative to other parts, and it is also the position with the highest requirement on the connection strength between it and the main frame. Therefore, by making the distance between the matching part and the connection port 1-2cm, the matching part and the connection port have a closer distance, which helps to ensure the connection stability between the limiting connection part and the matching part, thereby helping to ensure the installation stability of the water outlet waterway plate on the main frame, and in the embodiment in which the aforementioned elastic vibration damping structure is arranged between the limiting connection part and the matching part, the buffering effect of the elastic vibration damping structure can also be used to enhance the buffering and vibration damping effect of the water outlet waterway plate. Moreover, the distance of 1-2cm reserved between the matching part and the connection port is also sufficient for the limiting connection part to achieve a limiting connection with the matching part here.

[0020] 4. As a preferred embodiment of the present application, the ratio of the mass of the water inlet waterway plate to the mass of the water outlet waterway plate is 0.8-1.2, so that the masses of the water inlet waterway plate and the water outlet waterway plate are similar, avoiding a large difference in mass between the two and reducing the vibration reduction and noise reduction effect. At the same time, it also effectively prevents the water inlet waterway plate from being too large and the water outlet waterway plate from being too small, resulting in the water inlet waterway plate, the water outlet waterway plate, and the hot water pump being unable to obtain reliable support from the main frame.

[0032] In order to more clearly illustrate the overall concept of the present application, a detailed description is given below in an illustrative manner in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present application.

[0035] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] In the present application, unless otherwise clearly specified and limited, a first feature "above" or "below" a second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0037] In the embodiment of the present application, a vibration-reducing and noise-reducing water purifier is provided. For the convenience of explanation and understanding, the following contents provided in the present application are all explained on the basis of the illustrated product structure. Of course, those skilled in the art can understand that the above structure is only used as a specific example and schematic description, and cannot constitute a specific limitation on the technical solution provided in the present application.

[0038] Reference Figure 1 and Figure 2 As shown, a vibration-reducing and noise-reducing water purifier provided in the present application includes a main frame 1, a hot water pump 2, a water inlet waterway plate 3 and a water outlet waterway plate 4, the water inlet waterway plate 3 is provided with a water inlet pipe 31, the water outlet waterway plate 4 is provided with a water outlet pipe 41, the water inlet pipe 31 is connected to the water inlet of the hot water pump 2, the water outlet pipe 41 is connected to the water outlet of the hot water pump 2, the water inlet waterway plate 3 is separated from the main frame 1, the main frame 1 is provided with a limited connection part, the water outlet waterway plate 4 is provided with a matching part, and the main frame 1 is connected to the water outlet waterway plate 4 through the matching and limiting connection part.

[0039] The vibration and noise reduction water purifier provided in the present application is provided with a water inlet waterway plate 3 having a water inlet pipe 31, and a water outlet waterway plate 4 having a water outlet pipe 41. The water inlet pipe 31 is connected to the water inlet of the hot water pump 2, and the water outlet pipe 41 is connected to the water outlet of the hot water pump 2. In other words, the water inlet and the water outlet of the hot water pump 2 are respectively connected to the water inlet waterway plate 3 and the water outlet waterway plate 4 to achieve a cross-plate connection. In this way, the situation where the vibration main frequency of the water pump is consistent with the fixed frequency of a waterway plate can be changed. When the water inlet waterway plate 3 and the water outlet waterway plate 4 are each independent, their respective masses are greatly reduced compared to their masses when the two are combined into a whole waterway plate, and the fixed frequency will also be greatly reduced, which helps each to avoid the working frequency of the hot water pump 2, and further helps to avoid resonance with the hot water pump 2. The waterway structure of the water inlet waterway plate 3 and the water outlet waterway plate 4 changes little compared to a whole waterway plate, and can still meet the needs of large flow. In addition, the water inlet waterway plate 3 is separated from the main frame 1, and the water outlet waterway plate 4 is limited on the main frame 1. Therefore, compared with the method in which both the water inlet waterway plate 3 and the water outlet waterway plate 4 are in contact with the main frame 1, this solution makes the water inlet waterway plate 3 completely out of contact with the main frame 1, so that the water inlet waterway plate 3 cannot directly transmit the vibration to the main frame 1. Therefore, the degree of resonance generated by the main frame 1 is also greatly reduced, thereby effectively reducing the working noise of the whole machine and improving the user experience.

[0040] This solution does not limit the limiting cooperation mode between the limiting connection part and the cooperation part. For example, it can be rotation limiting, plug-in limiting, etc.

[0041] As a preferred embodiment of the present application, the water purifier further includes an elastic vibration reduction structure, which is arranged between the limiting connection part and the matching part to play a buffering and vibration reduction role between the water outlet waterway plate 4 and the main frame 1. It can be understood by those skilled in the art that the elastic vibration reduction structure is arranged between the limiting connection part and the matching part to play a buffering and vibration reduction role between the water outlet waterway plate 4 and the main frame 1. Therefore, compared with the hard connection between the water outlet waterway plate 4 and the main frame 1, under the buffering and vibration reduction effect of the elastic vibration reduction structure, the water outlet waterway plate 4 and the main frame 1 form an elastic soft connection. After the vibration energy of the hot water pump 2 during operation is transmitted to the water outlet waterway plate 4, the water outlet waterway plate 4 converts most of the vibration energy into the elastic potential energy of the elastic vibration reduction structure, and the vibration energy is greatly absorbed and attenuated by the elastic vibration reduction structure, thereby greatly reducing the vibration energy transmitted to the main frame 1, thereby effectively reducing the vibration of the whole machine and achieving the effect of noise reduction.

[0042] The specific structure of the limiting connection part and the matching part is not limited in this application, and includes but is not limited to the following embodiments:

[0043] Embodiment 1: One of the position-limiting connection part and the matching part is configured as a through hole, and the other is configured as a column adapted to the through hole, the column and the through hole are inserted and limited, and the elastic vibration reduction structure is configured as an elastic pad 5 sandwiched between the column and the inner wall of the through hole. Figures 3 to 7 As shown, this scheme schematically illustrates an embodiment in which the limiting connection part is a column 11 and the matching part is a through hole 42. During assembly, the elastic pad 5 is pre-installed in the through hole 42 or sleeved on the outside of the column 11, and then the through hole 42 on the water outlet waterway plate 4 and the column 11 on the main frame 1 are inserted and limited to achieve a limiting connection. At this time, the elastic pad 5 is clamped between the column 11 and the inner wall of the through hole 42.

[0044] More preferably, if Figure 5 and Figure 7As shown, a limiting end 12 is provided at the end of the column 11, and the limiting end 12 includes two symmetrically arranged limiting buckles 121. After the column 11 passes through the through hole 42, the limiting buckles 121 engage and limit the water outlet waterway plate 4. There is a gap between the two limiting buckles 121, and they can be deformed toward each other under the state of being applied with pressure to reduce the outline size of the limiting end 12. It can be understood by those skilled in the art that in the process of passing the limiting end 12 through the through hole 42, the two limiting buckles 121 are blocked by the edge of the through hole 42 and deform toward each other, and the outline size of the limiting end 12 is reduced and can pass through the through hole 42. After the limiting end 12 passes through the through hole 42, the two limiting buckles 121 are no longer squeezed and resume to be realized, and the limiting end 12 becomes larger so as to engage and limit with the end face of the through hole 42, thereby realizing the limitation of the water outlet waterway plate 4. This design improves the simplicity of the limiting connection between the limiting connection part and the matching part.

[0045] In addition, regarding the structure of the elastic pad 5, preferably, as Figure 7 and Figure 8 As shown, the elastic pad 5 includes an annular body 51 with an axial hole, and the two axial ends of the annular body 51 are respectively provided with positioning protrusions 52 extending radially outward, and the two positioning protrusions 52 respectively abut on the hole end surfaces at both ends of the through hole 42 to limit the elastic pad 5 from moving in the axial direction, and the column 11 passes through the axial hole. The elastic pad 5 includes an annular body 51 with an axial hole, so that the column 11 can achieve a limited fit with the through hole 42 by passing through the axial hole, and at the same time, the column 11 only contacts the elastic pad 5 but not the water outlet waterway plate 4. The two positioning protrusions 52 respectively abut on the hole end surfaces at both ends of the through hole 42 to limit the elastic pad 5 from moving in the axial direction, effectively preventing the elastic pad 5 from detaching from between the column 11 and the through hole 42 and losing the buffering and vibration absorbing function.

[0046] Embodiment 2: Although not shown in the drawings, one of the position-limiting connection part and the matching part can be configured as a slide groove, and the other can be configured as a slider matched with the slide groove. A stopper is provided in the slide groove, and the slider slides into the slide groove. The stopper cooperates with the slider stopper to limit the slider from sliding out of the slide groove. The elastic vibration-damping structure is configured as an elastic pad wrapped around the outside of the slider or attached to the inside of the slide groove. Different from the plug-in matching mode of the position-limiting connection part and the matching part in the aforementioned embodiment 1, in this embodiment, the position-limiting connection part and the matching part are slidably connected, and the slider is stopped by the stopper after sliding into the slide groove and is limited in the slide groove, thereby realizing the limitation of the main frame to the water outlet waterway plate, and the elastic vibration-damping structure is configured as an elastic pad wrapped around the outside of the slider or attached to the inside of the slide groove. The slider does not directly contact the inner wall of the slide groove, and then the elastic pad absorbs the vibration to achieve vibration reduction and noise reduction.

[0047] As a preferred implementation of the present application, Figure 3 As shown, the water outlet pipe 41 has a connection port 43 for connecting to the water outlet of the hot water pump 2, and the distance between the matching portion and the connection port 43 is L, 1cm≤L≤2cm. Those skilled in the art can understand that the water outlet pipe 41 has a connection port 43 for connecting to the water outlet of the hot water pump 2, and the vibration energy generated by the hot water pump 2 when working is transmitted to the cold water pump 7 through the connection port 43. Therefore, the vibration at the connection port 43 of the water outlet waterway plate 4 is the most obvious position relative to other parts, and it is also the position with the highest connection strength requirements with the main frame 1. Therefore, by making the distance between the matching portion and the connection port 43 1-2cm, taking the embodiment in which the matching portion is a through hole 42 as an example, the distance between the through hole 42 and the connection port 43 is 1-2cm. The distance L between them is 1-2cm, so that the matching part and the connection port 43 are at a closer distance, which helps to ensure the connection stability between the limiting connection part and the matching part, thereby helping to ensure the installation stability of the water outlet waterway plate 4 on the main frame 1, and in the embodiment in which the aforementioned elastic vibration damping structure is arranged between the limiting connection part and the matching part, the buffering effect of the elastic vibration damping structure can also be used to enhance the buffering and vibration damping effect of the water outlet waterway plate 4, and the distance of 1-2cm reserved between the matching part and the connection port 43 is also sufficient for the limiting connection part to achieve a limiting connection with the matching part here.

[0048] As a preferred embodiment of the present application, the ratio of the mass of the water inlet water circuit plate 3 to the mass of the water outlet water circuit plate 4 is 0.8-1.2, so that the masses of the water inlet water circuit plate 3 and the water outlet water circuit plate 4 are similar. For example, the ratio of the mass of the water inlet water circuit plate 3 to the mass of the water outlet water circuit plate 4 can be made to be 1, that is, the masses of the water inlet water circuit plate 3 and the water outlet water circuit plate 4 are equal, to avoid a large mass difference between the two, which causes the fixed frequency of the water inlet water circuit plate 3 and the water outlet water circuit plate 4 with a larger mass to be close to the working frequency of the hot water pump 2, especially to avoid the mass of the water outlet water circuit plate 4 being too large, which causes its fixed frequency to be close to the working frequency of the hot water pump 2, resulting in reduced vibration reduction and noise reduction effects. At the same time, it also effectively prevents the water inlet water circuit plate 3 from being too large and the water outlet water circuit plate 4 from being too small, resulting in the water inlet water circuit plate 3, the water outlet water circuit plate 4, and the hot water pump 2 being unable to obtain reliable support from the main frame 1 due to the limited connection between the water outlet water circuit plate 4 and the main frame 1.

[0049] As a preferred implementation of the present application, Figure 1 and Figure 2As shown, the water purifier further includes a water storage tank 6 installed in the main frame 1, the water storage tank 6 is provided with a water supply pipe 61 with a water supply outlet, the water supply pipe 61 is connected to the water inlet pipeline 31, and the water inlet waterway plate 3 is separated from the main frame 1 by being connected to the water supply pipe 61 and the hot water pump 2 respectively. Specifically, the water storage tank 6 can be used as a structure for storing raw water, thereby forming a water source supply structure when the whole machine is working; of course, the water storage tank 6 can also be used as a structure for storing room temperature purified water or warm water, which is not limited here. The water storage tank 6 is provided with a water supply pipe 61 with a water supply outlet, and the water supply pipe 61 is connected to the water inlet pipeline 31. Since the water outlet pipeline 41 is connected to the water outlet of the hot water pump 2, the water inlet waterway plate 3 is separated from the main frame 1 by connecting to the water supply pipe 61 and the hot water pump 2 respectively, thereby ensuring the assembly stability of the water inlet waterway plate 3. Moreover, the water supply pipe 61 not only supports the water inlet waterway plate 3, but also transports water from the water storage tank 6 to the water inlet waterway plate 3, thereby achieving the effect of one component and multiple functions, which helps to simplify the waterway structure.

[0050] More preferably, if Figure 1 and Figure 3 As shown, the water purifier further includes a filter element, an instant heating element, and a cold water pump 7 respectively installed on the main frame 1, the water storage tank 6 is configured as an insulation box with an insulation function, the clean water outlet of the filter element is connected to the water inlet of the instant heating element, the water outlet of the instant heating element is connected to the insulation box, the water outlet of the instant heating element is connected to the insulation box, the water outlet waterway plate 4 is provided with a normal temperature water pipeline 44, the water inlet of the cold water pump 7 is connected to the clean water outlet of the filter element, and the water outlet of the cold water pump 7 is connected to the water outlet pipeline 41 through the normal temperature water pipeline 44. The water storage tank 6 is configured as an insulation box with an insulation function, the water outlet of the instant heating element is connected to the insulation box, so that the hot water heated by the instant heating element can be transported to the water storage tank 6 for insulation storage, so that when hot water is needed next time, warm water can be directly obtained from the water storage tank 6 for heating, which shortens the heating time and improves the corresponding water output capacity. In addition, the water outlet waterway plate 4 is provided with a normal temperature water pipeline 44, the water inlet of the cold water pump 7 is connected with the clean water outlet of the filter element, and the water outlet of the cold water pump 7 is connected with the water outlet pipeline 41 through the normal temperature water pipeline 44. Therefore, when the hot water pump 2 pumps the warm water in the water storage tank 6 to the water outlet pipeline 41, the normal temperature clean water produced by the filter element can also be pumped to the water outlet pipeline 41 through the cold water pump 7, so that the warm water and the normal temperature water are mixed and then transported to the instant heating body for rapid heating, which helps to quickly heat the instant heating body to the temperature required by the user.
